This is in Arizona.
The other day I was in my attic to lay some cat5 and noticed the ac
lines in the attic running from the outside unit to the indoor part do
not have any insulation on it. The line outside form the outside unit
to the wall of the house do have insulation around it.
The attic gets quite toasty and I'd think it would be a good idea to
insulate them ? They are very easy to access.
What do you think ?
Also, the lines are hanging from one end to the other for quite a bit
of distance and not supported.
While I Was up there one of the units kicked in and I noticed the line
moving a little bit when the unit started.(then stopped moving, so
only moved caused by the start) Probably not good either ? What do I
use to hang it more secure ? The roof is a wood frame roof with tile
on top.
Well, Hope you hvac guru's can give me some advice,

A wide band pipe plastic pipe strap will work just fine every 4 feet.
Don't bind it too tight. It needs expansion and contraction room.
If you screw it up, contact Paul and he will straighten you out. :-p

Definitely a good idea to insulate the lines. Where I am (western NYS) they
sell foam wrap at the hardware stores. As to securing the lines, after the
tubing is foam wrapped, it's not likely to rub on anything and wear through.
So, strapping it down is less important, then.
